cgroup: separate out interface file creation from css creation
Currently, interface files are created when a css is created depending
on whether @visible is set. This patch separates out the two into
separate steps to help code refactoring and eventually allow cgroups
which aren't visible through cgroup fs.
Move css_populate_dir() out of create_css() and drop @visible. While
at it, rename the function to css_create() for consistency.
